UTF-8 is the only reasonable choice for such things.

The biggest problem with encoded words is that they admit the possibility of
using multiple charsets for a single field. You really don't want to go there.

Doesn't necessarily follow. Conversion from UTF-8 to an encoded word
is straightforward. Conversion in the other direction is anything but.
